Main Article Content


Pellet Biopolymer Polyvinyl Alcohol/Alginate/Glutaraldehyde impregnated with BPAC has been successfully synthesized. The morphology of pellet biopolymer was observed using SEM and mechanical strength of pellet was investigated using Hydraulic Impact Resistance. The density of pellet was also investigated. The result shows that the pellets have a round shape, springy texture, and water content presence inside the pellet. Pellet biopolymer without BPAC have an white gel-like bead, pellet with 0.5 g of BPAC was dark gray, and pellet with 1 g of BPAC was light gray. The SEM image of pellet biopolymer with 0.5 g of BPAC shows that the BPAC existed on the surface of pellet biopolymer. However, the SEM image of pellet biopolymer with 1 g of BPAC shows that almost all of the BPAC coated into the pellet biopolymer. The obtained pellet biopolymer impregnated with BPAC could adsorb the copper (II) ion from aqueous solution.
